HERNIAL TRUSS.

parts, Figure lis a front view in perspective of a truss, illustrating my improvements. Fig. 2 is a similar view, but showing the billetstrap in part disconnected and the perineal strap disengaged and by dotted lines showing the capacity ofthe pad for change of position in adjustment. Fig. 3 represents a transverse central section of the pad audits accompanying parts as I construct them. This figure also shows a transversesection of the belt where it is embraced between the pad and its securing-piece.

tion in detail.

A indicates a belt. The portion B of this belt consists of athin spring B2, usually madev of metal incased in a leather or other good covering B2. The portion C of this belt consists of a flexible piece, usually of webbing. This may or may not be elastic in the direction of its length. The free end of this portion O is provided with an end piece D, known as a tongue The parts alreadydescribed were all old and well known previous to my invention.

Upon the truss and preferably upon the portion B, near its free end, I locate a staple E, whose ends E2 E2 are respectively secured to the truss. The space E3 ofthe staple admits the tongue. The pad II proper may be of any desired construction, 'and it may be a hard or n a soft pad, as desired. To the back of this pad I affix a broad piece K of stiff strong material, preferably metal. One end K2 of this piece .K is connected to one portion of the pad by a set-screw M and the other end K3 of this piece K is connected to the pad by asetscrew N. The portion B of the truss passes strap P is placed.

between the pad H proper and this piece K, and this piece is long enough so that the. portion B may pass beneath the piece K and over the pad when the length of piece K makes vquite -an oblique angle to the lengthof-portion B. By such a lengthening-I am enabled to vary the angle which this piece and the pad make with portion B by loosening the set-screws M and N and then changing the position of the pad. I am thus enabled to adapt the angle and position of the pad to the need of thepatient-that is, to the proper retention and pressure upon the part afflicted with hernia. 2 I indicate by solid lines one position which the p ad may be caused to take and in dotted lines another position which the pad may be made to assume. The pad may be placed in many intermediate positions, as necessity dictates. When such trusses are employed, the

perineal strap P is with scarcely an exception employed. The construction of this strap may be varied. When present, I provide means for its retention. A well-known Thus in Fig.

mode of connecting it at rear to the belt is shown in Figs. 1 and .2.A Atthe front I provide the following means for its at tachment-f namely, I form the set-screw with an extension M2 between an annular flange MS and its free enlarged end M4. Over this extension the opening S of the part P2 of the perineal The pressure on this strap draws it down and draws the part P2 down,

and the extension M2 enters the slot S2 and isv 85 locked therein. To disengage the part S2 from the extens-ion M2, the operation is reversed.

The mode of connection of the perineal strap at the'front is very simple, economical, and convenient. At the center of the piece K, I erect a stud T, having a contracted neck T2. This stud is to be received into the desired hole D2 of the tongue D.

The mode in which my invention operates is inl general as follows: Thepad is moved to the proper place on the belt and set at the correct angle to accomplish the obj ectl for which it is present. The set-screws M and N are now tightened and the belt tightly clamped between piece K and the pad I-I. The truss is duly located in position upon the body of the person who is to wear it. then drawn forward over the belt and beneath the stapleE and after being drawn taut is too The tongue is fastened over and on the stud T. The front end of the perineal strap is brought forward and up and duly connected, as prescribed, to the screw M. The operation is now completed.

It will be observed that the adjustable piece K, in connectionwith its screws M and N and with the stud T, has, first, a capacity for longitudinal adjustment along the belt; secondly, a capacity for any desirable angulated position relative to the belt 5 thirdly, furnishes means for the attachment of the perineal strap at front and of the tongue of the belt. Nor is this all. By withdrawing the screws M and N the pad can be removed from thc belt and reattached thereto in a reversed position. Such change is the work of but a few minutes. The truss has thus been reversed. Thus this feature of my improvement renders the truss being capable of use :for hernia in the right or left inguinal region, as necessary.v That my invention is also sinin ple and economical is obvious.

That I claim as new and of my invention, and desire to secure by Letters Patent,

l.. ln a truss, a pad, a belt, a clamping-piece extending across the belt on one side and in contact therewith, means for securing the said clamping-piece at its ends directly to the pad tohold the back face of the pad in contact with the inner face of the belt, the said clamping-face being of a length to enable the pad to be shifted into diiferent angular positions, said clamping-piece having a central stud, said belt having a tongue to engage the central stud and a staple on the belt through which the tongue passes substantially as described.

In a truss, a pad, a belt, a clamping-piece extending across the belt on one side and in contact therewith, means for securing the said clamping-piece at its ends directly to the pad to hold the back face of the pad in contact with the inner face of the belt, the said clamping-face being of a length to enable the pad to be shifted into different angular posi tions, said cla1nping-piece having a central stud, said belt having a tongue to engage the central stud, a staple on the belt through which the tongue passes and a perincal strap secured to the lower end of the clampingpiecc, substantially as described.
